Snow to re-coat parts of northeastern US this weekend

March 18,2017, 9:57:56AM,EDT

Winter will continue to hold its ground this weekend before the
official arrival of spring with snow and areas of slippery travel
returning to parts of the northeastern United States.

A repeat of
the Blizzard of 2017 will not occur. However, enough snow can fall to
create slick spots and hinder blizzard recovery efforts.
Two
separate bands of snow and rain will sweep from the Great Lakes to
southern New England and the northern mid-Atlantic through Saturday
night.
The snow is expected to leave a slushy coating to 2 inches.
The highest amounts will fall on grassy and elevated surfaces, but
slick travel can still pose risks to motorists in some communities.

During the daylight hours, the snow will
have trouble sticking to paved surfaces due to the stronger March sun
outside of any heavier bursts of snow.
More slick spots are expected on Saturday night under the cover of darkness and as the intensity of the snow increases.
There will be two key areas of concern for a couple inches of snowfall and slippery travel.
One
band of snow that led to slick roads in southeastern Michigan on
Saturday morning is expected to re-intensify across south-central
Pennsylvania on Saturday evening before dropping southward into northern
Virginia.RELATED:Photos: Blizzard of 2017 drops 42 inches of snow, brings travel to standstill in northeastern USFrom rainbows to fogbows: How do these unique phenomena form?Will next cold wave set stage for ice, snow in northeastern US late next week?
While there can be rain at the its
onset, portions of I-99, I-81, I-70 and I-270 can turn slushy for a
time. This includes in Johnstown and Harrisburg, Pennsylvania;
Frederick, Maryland; Martinsburg, West Virginia; and Winchester,
Virginia.
“As temperatures fall, rain in Washington, D.C., this
evening will change over to a period of snow early Sunday morning,”
AccuWeather Meteorologist Steve Travis said.
“The snow will most
likely not accumulate in the district itself as temperatures will remain
above freezing, but in the northwest suburbs, there can be a slushy
coating to an inch or so of accumulation.”
Only if the snow falls heavy for a time would it be able to lightly whiten the district, especially non-paved surfaces.

Wet snow can mix with the rain across the southern suburbs, but plain rain should just dampen Richmond and Norfolk, Virginia.
Where
the snow does not create travel problems, residents should get their
cameras ready. A gorgeous winter wonderland scene will result as the wet
nature of the snow will allow it to cling to everything.
As the
storm strengthens offshore, a separate area of steadier snow will unfold
from eastern Long Island to Cape Cod, Massachusetts, on Saturday night
into Sunday morning.
A few inches of snow and slippery travel are expected in these areas.
Increasingly
windy conditions will accompany the snow in southeastern New England,
whipping the snow around and further reducing visibility for motorists.

Seas will build as the winds strengthen, creating hazards for those with shipping interests.
The two snow zones will pass in between New York City and Philadelphia, limiting travel disruptions.
“While
there can be some slick spots into early Sunday morning in the New York
City area, the snow will not fall heavily enough to cause major travel
problems," AccuWeather Meteorologist Brian Thompson said.
"It will be a struggle to even see an inch of snow in New York City and Philadelphia, even on non-paved surfaces.”
The
snow in southeastern New England will taper off for Sunday afternoon as
high pressure brings the weekend to an end on a dry note across the
rest of the Northeast.
Brutal cold will not follow immediately in the wake of the storm.
Temperatures
on Sunday will instead rebound back to near 40 F in southern New
England to the lower 50s in Baltimore and Washington, D.C.
Those
heading to Washington, D.C., for the National Cherry Blossom Festival
will enjoy the return of some sunshine on Sunday afternoon.
The
opening date of the renowned festival was pushed back from Wednesday,
March 15, “due to setup delays caused by the storm,” organizers
announced on Twitter.
The
milder temperatures will quickly cause the snow from earlier this
weekend to start to melt. However, residents should then watch for areas
of re-freeze on untreated surfaces at night.Another blast of cold air will not be far behind.
